what honda said:when u say tube..do u mean the egr pipe?
theres only one metal pipe that connects to the headers to the
intake manfiold. get a can of electrical cleaner spray.
take off the egr pipe and clean that **** first before u buy one
im having the same problem rite now
reading 10 long flashes and 5 short.
comes on in a blue moon. just too lazy to do it myself
and i jammed the egr bolt to the obx headers so i know its stripped.
